Note:

In general, X-forwarded-for is used to record agent information, each through a level of agent (except anonymous proxy), the proxy server will be the source IP of the request is appended in X-forwarded-for from 4. 4.4 1.1. 1.1 2.2. 2.2 3.3. 3.3 represents the request by 1. 1.1. 1 issued, after three layers of agent, the first layer is 2. 2.2. 2, the second floor is 3. 3.3. 3, and the source of this request is IP4. 4.4
1.1. 1.1 So, if there is only one layer of proxy, the value of these two headers is the same.
